Piezoelectric laminate, surface acoustic wave device, thin-film piezoelectric resonator, and piezoelectric actuator
A piezoelectric laminate (100) including a base (1) and a first piezoelectric layer (3) formed above the base (1) and including potassium sodium niobate. The first piezoelectric layer (3) is characterised by a compositional formula (K a Na 1-a ) x NbO 3 , "a" and "x" in the compo...

| Zusammenfassung: | A piezoelectric laminate (100) including a base (1) and a first piezoelectric layer (3) formed above the base (1) and including potassium sodium niobate. The first piezoelectric layer (3) is characterised by a compositional formula (K a Na 1-a ) x NbO 3 , "a" and "x" in the compositional formula being respectively 0.1 |
